Although these sensors are known for their precision in stationary systems, their reliability under fluctuating flow conditions has remained unclear. To validate their accuracy, ultrasonic measurements were compared with both automated image analysis via a Python algorithm and manual video evaluation. Results show that ultrasonic sensors maintain high precision at moderate gas loads and with small hole diameters. Increased gas loads and turbulence, however, reduced measurement accuracy due to signal scattering. The findings highlight the potential of ultrasonic sensing for real‐time, noninvasive monitoring in dynamic multiphase systems.</jats:p>"}],"status":"public","publication":"Chemie Ingenieur Technik","type":"journal_article"}
